He only likes being touched for so long before he becomes evil and hisses and/or tries to bite. If one is smart, one never tries to pet his belly. Well, unless one has decided that only having the full use of one hand is acceptable.
Ah...Fisher was like that too until recently. I know, you start petting him and then he turns his head quickly as if to say "Im gonna bite you, okay?" He also still does not like it if I reach directly over his head with my hand. He needs to see me extending my hand before he will allow me to pet him. But lately, he rubs against me and I can even stroke his belly a bit. You have had Jeffrey for years, right?
